As the name implies, the MTSRN is a network of reference stations that collect GNSS observations and send them in real time to a central processing unit sitting in a cloud server where the processor combines the observations and compute a network (or subset) solution. From this network solution the observations errors and corrections are computed and broadcast to rovers (that are logged in to MTSRN NTRIP Caster via internet) within the bounds of the network by mimicking a virtual reference station (VRS) nearby as if the rover is getting correction with reference to the VRS. The user receives centimeter accuracy positional coordinates (latitude, longitude, and ellipsoid height) in the current horizontal datum, NAD 83 (2011), 2010.0. Users can receive orthometric height in the current vertical datum, NAVD 88 by using a current geoid model such as GEOID18 in the receiver.

MTSRN has five existing subnets. These are: Northeast Montana (NEMT), Northcentral Montana (NCMT), Northwest Montana (NWMT), Southwest Montana (SWMT), and Southcentral Montana (SCMT). Users can receive network-based corrections from these subnets. MTSRN also provides solutions with reference to stations individually.
